IMPROVEMENT IN TELEGRAPH-POLES.

Specification forming part of Letters Patent No. 203,746, dated May 14,1878; application filed April 94, 1878.

To all whom it may concern:

Be it known that I, WALTER O. LEWIS, of No. 20 Pierrepont street, in thecity of Brooklyn, county of Kings, and State of New York, have inventeda new and useful Improvement in Telegraph-Wire Poles or Supports, ofwhich the following is a specification:

The invention relates to a telegraph-wire support which has for its ownbasis or means of support the ordinary iron street-gas lamppost.

It consists in a combined lamp-post and telegraph-pole or telegraph-wiresupport, the telegraph-pole being constructed of rods, pipes, orangle-irons secured to the lamp-post and provided above withbrace-plates. 4

In the accompanying drawing, Figure 1 is an elevation of the lamp andtelegraph post or pole. Fig. 2 is a tie or brace plate, E, forastructure in which four (4) rods or angle-irons are employed; and Fig. 3is a tie or base plate, E, for a structure in which only three (3) rods,pipe, or angle-irons are used.

B represents that part of the lamp-post which is buried in the ground tosupport the superstructure. In case where considerable weight and strainis to be put upon the post or pole, by attaching thereto a number ofwires, this base may be made longer and stronger, or may be otherwiseprovided in any usual way with devices, or be made in any known shapesuitable to give the required stability. A are the rods, pipe, orangle-irons which start from a clamp or band, C, fitted thereto, so asto hold them firmly in position and against the body B of the lamp-post.At intervals clamps or bands 0 O, which may be either rings slipped intoplace or hinged straps secured in any known and suitable way, hold 'allthe angle-irons, pipe, or rods firmly against the body and stem of thelamp-post, especially at the top, where they expand or are deflectedoutward to give room for the lamp, as at L. This point, being theweakest, or that which will receive the strain of the supported wires ina way to resist flexure least under ordinary strains, may be re-enforcedby duplicating or enlarging the rods, pipe, or angle-irons from, say,the second band or clamp from the top to the first tie or brace plate Eas far as increased strength is required, the ends of the duplicateparts, if any, being secured by the clamp and brace-plate, and the clampat L also binding them together.

At top the rods may end in the collar- 0, which may receive a topmast orpole, P, composed either of wood, which will be preferable for itsnon-conducting qualities, or of tubular iron, to the top of which theusual cross-bars, provided with the usual insulating appliances, are tobe attached.

The advantages of this invention are that one foundation or pedestaldoes double duty, first, as lamp-post, and, second, as a base for atelegraph-pole, making but one obstruction in the street, and savingexpense as well; also,

the clamps and brace-plates may be used to climb by or on, and should beso placed as to be conveniently and securely reached by the vfeet forthat purpose.

The lamp, of course, occupies its usual posi tion at the point where therods, pipes, or angles-irons expand, and then, turning at an angle, drawinto the first base-plate E.

I claim as my invention- The combined lamp-post and telegraph-pole shownanddescribed, consisting of the lamppost body B and base B, and rods,pipes, or angle-irons A, secured to the body of thelamppost by the bandsor clamps O, and provided with the tie or brace plates E or E.
